Data Table

SK: “All cancers” does not include non-melanoma skin cancers diagnosed in SK. Denominator includes incident cases for which stage is recorded as “Not Applicable” since SK does not differentiate between “Not Applicable” and “Not Available” categories.

ON: Stage 0 excluded.

NB: From 2008 onward, only the 4 most common cancers (breast, colorectal, lung and prostate) are staged.

NL: Staging not complete for 2014 so it is not possible to report on “All cancers (2013).”

SK: “All cancers” does not include non-melanoma skin cancers diagnosed in SK. Denominator includes incident cases for which stage is recorded as “Not Applicable” since SK does not differentiate between “Not Applicable” and “Not Available” categories.

ON: Stage 0 excluded.

NB: From 2008 onward, only the 4 most common cancers (breast, colorectal, lung and prostate) are staged.

NL: Staging not complete for 2014 so it is not possible to report on “All cancers (2013).”

AB: Hematology, sarcoma and melanoma morphologies were removed from the site-specific cancers. All 2012-2013 invasive primaries are collaboratively staged and once coded there should be no cases with missing/not available stage values. Currently “Not Available” indicates the number of cases that have a missing stage at the time of data pull as the registry status was not complete and staging information is still to come. Certain skin cancers (C44 codes) with morphologies other than basal-squamous are not staged according to Alberta Cancer Registry (ACR) rules. For this indicator, codes 8002, 8073 and 8803 are included as NSCLC.

SK: “All cancers” do not include non-melanoma skin cancers diagnosed in the province (topography codes C44.0 to C44.9 and histology codes not in 8720-8790). The denominator includes incident cases for which stage is recorded as “Not Applicable” since SK does not differentiate between “Not Applicable” and “Not Available” categories.

ON: Data submitted exclude stage 0 cases.

NB: From 2008 onwards, only the four most common cancers (breast, colorectal, lung and prostate cancers) are staged.

NL: Staging is not complete for 2014 so it is not possible to report on all cancers (2013).

Notes:

The group stages for cancer incident cases were classified by AJCC Cancer Staging 7th edition.

By AJCC, cancer incident cases are categorized in terms of stage as:

Stageable: including stage 0, stage I through stage IV, stage unknown

Not Applicable: Not stageable through AJCC

Not Available: Cases for which stage data is not available or invalid

Unknown: Cases for which there is insufficient information to ascertain a definitive stage

Stage 0 includes in-situ and invasive cancer cases. Stage occult for lung cancer cases are included as well.
